' AUTOMATIC SIPHON.

Application filed July 10, 1922. Serial No. 574,121.

T all whom it may concern:

Be it known that I, CHARLES L. GRAVETT, a citizen of the United States. residing at Roanoke, in the county of Roanoke and State of Virginia, have invented new and useful Improvements in Automatic Siphons, of which the following is a specification.

My invention relates to siphons in which the action of the siphon is started without first sucking the air from the pipe or tube,

and consists mainly of an apparatus as hereinafter described attached to the immersion end of the tube. All that is necessary in order that the siphon commence operating is to immerse the said end of the tube in the fluid.

Reference may be had to the accompanying drawing in which: Fig. 1 is a sectional view of the entire apparatus, and Fig. 2,

is a cross section taken on the line A* A, Fig. 1. Similar numerals refer to similar parts on the several views.

In Fig. 1, 1 and 2 indicate vessels in which a transfer of liquid is to be made, 3,

is a cylindrical tube having a tightly fitted head at its upper end 4, and at its lower end the plug 5, with the serrated base rim 7, and the orifice 6. Extending upwards about half the length of the tube 3, is the pipe 9, which extends through the lower plug 5, and is open. Extending through the top head 4, and reaching downwards to the end of the lower pipe 9, is the upper pipe 10, which extends through the top head and connects with the siphon tube 11. Fig. 2, shows the relative. positions of the ends of the pipes 9 and 10 at the point of their meeting.

In operation, the apparatus having been placed in the liquid in the position shown, the fluid at once passes through the orifice 6 and the lower pipe 9 until it has reached a level at a point at the end of the pipe 9 and the pipe end 10, thereby compressing the air in the chamber 12, the fluid at once continuing to pass on through the siphon tube 11.

I claim:

1. The combination of a tube having end pieces through which extend approximately half the length of the tube, two separate smaller tubes or pipes, whose meeting ends overlap, and the upper pipe extending to form a connection with a siphon tube, and an orifice extending through the lower end piece.

2. The combination of an air-tight chamher, a siphon tube extending half-way downwards in said chamber, and a tube extending from the lower end of the chamber to the meeting place of the aforesaid tube and whose ends overlap, and an additional openingiir orifice in the lower end of said chamber.
